At first 48 hours (0–6)

Hematocrit decrease > 10% (from admission) BUN increase > 5 mg/dL despite IV fluids Serum calcium < 8.0 mg/dL (2.0 mmol/L) Arterial PaO₂ < 60 mmHg (without lung disease) Base deficit > 4 mEq/L Estimated fluid sequestration > 6 L

Ranson score

Ranson's criteria were developed before modern ICU severity scores; they remain a teaching framework for understanding systemic complications of pancreatitis.

Gallstone pancreatitis uses a modified Ranson set; BISAP, APACHE II, and CT severity index add prognostic information. Arterial blood gas and precise fluid balance may not be available in all settings.
